| Abstract: | Based on the theory of the time scales and topological degree theory,by using continuation theorem of coincidence degree theory and some skills of integral inequalities on time scales,the sufficient condition of the existence of periodic solutions for a non-autonomous predator-prey system with time delays on time scales is obtained.The obtained result has practical significance and application value in ecological management. |
